摘要： The electromagnetic actuator is a linear electromagnetic actuator in which the relative position between a slide table that supports permanent magnets thereon and a guide rail that supports a coil, which is arranged in confronting relation to the permanent magnets, is displaced by means of a thrust force generated by a current flowing through the coil. The coil is disposed on the guide rail through a low coercive force magnetizable material body, the coercive force of which is lower than a predetermined value. Consequently, generation of residual magnetization can be suppressed, and an influence on the thrust force caused by such residual magnetization can also be suppressed.

摘要： An actuator drive control apparatus is equipped with a movement distance setting means for setting a movement distance of a displaceable member, a movement time setting means for setting a movement time, a target value calculating means for calculating a target value of a displacement amount or a displacement velocity of the displaceable member at an arbitrary timing based on the movement distance and the movement time, and a drive controller for generating driving power based on the displacement amount or the displacement velocity target value of the displaceable member and sending the drive power to an actuator.

摘要： A linear actuator displaces a relative position between a guide rail and a slide table, which is arranged in confronting relation to the guide rail. Projections are formed on opposite end sides of the guide rail, the projections extending along a direction of displacement and projecting toward the slide table. The slide table is disposed between the projections on the opposite end sides of the guide rail, with rigid balls being interposed therebetween. Guide grooves and guide grooves, which rollably support the balls, are provided on the projections on the opposite end sides of the guide rail and on the slide table. The guide grooves and the guide grooves apply, on the balls, a pressure caused by a magnetic attractive force of permanent magnets.
